Feb. 8 updates

3:50 p.m. ET: The Boston Celtics have formally signed free-agent center Greg Monroe, the team announced. Monroe, who originally agreed to sign with Boston last week after securing a buyout agreement with the Phoenix Suns, had to wait while the Celtics navigated the trade deadline before being inked to Boston's final roster spot.

8:43 a.m. ET: The New York Knicks will continue to try to find a trade for exiled center Joakim Noah on Thursday. Assuming that doesn't happen, opposing executives expect OKC and Minnesota will be among the teams interested in Noah if he's waived or bought out by the Knicks, league sources told ESPN's Ian Begley. As of earlier this week, Noah remained opposed to a buyout, sources say.

1:50 a.m. ET: The Memphis Grizzlies are still holding out for a first-round pick to move Tyreke Evans -- and Boston, Denver and Philadelphia have resisted offers beyond either a young player or a second-rounder, league sources told ESPN's Adrian Wojnarowski. First-rounders have never been gripped so tightly in the league.

1:38 a.m. ET: Teams reaching out to the Memphis Grizzlies on Marc Gasol have been consistently shut down, league sources told ESPN's Adrian Wojnarowski. The Grizzlies refuse to discuss trades on the franchise center.

9:38 a.m. ET: After Tuesday's loss to the Orlando Magic, LeBron James said he will not waive his no-trade clause ahead of Thursday's 3 p.m. ET trade deadline. "I'm here for the long haul," James said. "I'm here for this season right now, [to] try to figure out ways we can still compete. I couldn't give up on my teammates like that."

11:12 a.m. ET: If the Golden State Warriors can create a max salary slot this offseason, the defending champs could position themselves to secure a meeting with LeBron James, league sources told ESPN's Chris Haynes. It's worth noting, however, that there is no indication at this time that Golden State is evaluating such options to acquire the four-time MVP. ESPN NBA front office insider Bobby Marks detailed the moves -- some more complicated than others -- that could land King James with Golden State.

10:45 a.m. ET: Exiled New York Knicks center Joakim Noah won't be required to return to the team before the passing of the Feb. 8 NBA trade deadline, league sources told ESPN's Adrian Wojnarowski. The Knicks and Noah's representation discussed his status Wednesday and agreed that Noah would stay away from the team until the front office can exhaust any trade possibilities between now and the deadline, league sources said.
